ANVIL ATTACHMENT.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed June 18, 1904- Serial No. 212,283.

To all whmn it may concern- Be it known that we, OTTO FRANoEs HEER and JOHN GAMBER, citizens of the United States, and residents of \Vashington, in the county of Washington and State of Pennsylvania, have invented a new and Improved Anvil Attachment, of which the following is a full, clear, and exact descri tion.

Horseshoes are ordinarily locked out at a factory, and when received by the blacksmith the blanks are without toe and heel calks or clips.

The principal object of our invention is to aid in the necessary operations in preparing the shoe or blank before it is put upon the foot of a horse and to conveniently associate with each other in an attachment to be applied to anvils means for performing the several operations necessary in preparing shoes for application to horses.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of an anvil with our invention applied thereto. Fig. 2 is a perspective view of a steel plate which may be used on our attachment. Fig. 3 is a transverse sectional view of the plate shown in Fig. 2. Fig. 4 is an end View of the anvil, showing the attachment partly in section on the line 4 4 of Fig. 5. Fig. 5 is a side view of the attachment, and Fig. 6 is a perspective view of a plate which may be used on the attachment as shown in Fig. 1.

In the drawings, (1, represents an anvil of any desired construction and size, and B represents the attachment, the body I) of which serves as an anvil. The body I) is secured to the anvil a by means of an adjustable fastening device 0, which comprises bars 0 and 0. These bars are preferably of two kinds, one kind being placed at the ends of the anvil a and the other at the sides, the former having a flat surface for engagement with the anvil and the latter being adjustably connected to the former ones. The adjustment is preferably secured by means of screws 0 which act upon the one pair of bars and which may be loosened to allow the device to be raised or lowered or entirely removed.

A projection 0 as shown in Fig. 4, extends in one direction from the support, preferably rearwardly, and on this extension is secured an upwardly-extending projection 0 upon which the body I) is mounted. In the construction shown the projection c is secured to the sup ort by means of a screw 0 and the body is secured with respect to the anvil a by means of screws 0 and 0 I The body I) is provided with a flat surface I), adapted to receive a horseshoe and hold it while the heel-calks are being formed by bending the blank. I) is a projection on the back of this part of the body 1;, so shaped as to permit the blank to be bent to the proper angle to form the calks by merely hammering on the ends of the blank when placed in the proper position on the bending surface I) b is an upwardly-extending portion of the body I), having a portion of its upper surface flat and the remaining portion thereof inclined downwardly and forwardly, as shown. Upon the top of the portion b is a steel plate b which is of a shape corresponding to that of the upper surface of the extension and is secured thereto by means of a set-screw b and by an additional holding device in the shape of a projection b, fitting in a groove on the top of the portion W. The slanting surface I) of the steel plate I) is for use in sharpening the calks, and the flat surface thereof is for forming clips or toeieces on the shoes. For finishing square cal s a steel plate B such as that represented in Figs. 2 and 3, is used. This plate B has its upper surface flat throughout and is so shaped that when applied to the extension b a flat upper face will be given to the whole top surfac of the extension b 1 A pair of passages b and b are formed in the upwardly-extending portion b These passages lead to recesses formed in the upper part of the body I) and are for receiving the clip or toe-piece of the shoe while the toecalks are being drawn. One of these openings is larger than the other and is used for larger-sized shoes, while the other is for smaller-sized shoes. Upon the flat surface of the body b, directly in front of these passages, is removably secured a steel plate 1), upon which the calks rest when being drawn. When the toe-calk is being drawn, the clip or toe-piece projects into one of the openings 1) or b and the body of the shoe rests against the extension 5 6 is a hardy which is re movably mounted and held by a set-screw Z) in a projection 5 extending upwardly from the top of the body. The extension 6 has at its inner end an overhanging portion 19 and the projection b has at its outer side a similar overhanging portion 6 Under these overhanging portions the shoe is passed when upon the surface b and during the time the blank is bent to form heelcalks, so that the shoe will be held thereby and the operators hand relieved from any jar that would otherwise be caused by the hammering.

(1 represents in a general way a device for holding a shoe against the body I) while the calks are being sharpened or for any other desired purpose. It comprises an arm (1, pivotally mounted on the body I) and provided with a jaw d of sufficient width to extend across a shoe and firmly holdv it against the said body. In the form illustrated this device is provided with a bar (1 attached to the main part of the clamp and extending downwardly and terminating in a treadle d (1 is a spring secured at any convenient point to a stationary part of the device and having a shoe 0Z fitting over and riding upon an edge of the bar (1 The operation of finishing a shoe on the device will be obvious. The heel-calks of the shoe are formed by hammering after dropping the blank onto the surface I) through the slot between the projection 11 and the overhanging portion b of the extension 12 and sliding it under the overhanging portions 5 and 5 which serve as a clamp to hold the blank and prevent jar on the users hand. By bending the ends of the blank over the projection the desired angles to form the calks are easily obtained without any special attention upon the part of the workmen. The shoe is next placed against the extension 5 with the bent ends resting upon the plate 6, when the calks are drawn by hammering upon them. After the calks are drawn the shoe is placed in the position shown by dotted lines in Fig. 4 with the calks on the inclined face of the plate 6 and is held in this position by operating the treadle d to force the jaw (1 up into engagement with the shoe, when the calks may be sharpened in the usual manner. If square calks are to be formed, the plate B (shown in Fig. 2) will be substituted for the plate 6 (shown in Fig. 1,) which will provide for the rectangular corners desired. When the foot is taken off the treadle d, the spring (P will force the parts out of the position shown in Fig. 1, where they will be entirely out of the way and will permit further operations upon the shoe as desired. The clip or toe piece of the shoe is formed on the surface or B of the plates 6 or B in the usual manner either before or after forming the heel-calks. The toe-calks having been formed on the shoes in the usual manner by welding, the shoe is placed against the extension 6 with the clip or toe-piece proj ecting into one of the openings b or 5 and the calk resting upon the plate I), and by performing the usual operations upon them by hammering the calk is drawn. The shoe is then held by the jaw d with the calk upon the inclined surface of the plate I) and sharpened by hammering upon it, as usual. It will be seen that by this arrangement the shoe is securely held in place during the operation of drawing and sharpening the toe-calk and that there is no danger of breaking off the clip. The hardy b is very advantageously located for cutting off the rough edges sometimes left by the calk-sharpening operation. Heretofore the operator has been obliged to place the hardy in the ordinary anvil for each toe, as it is in his way for the other operations and has to be removed; but by our construction the hardy is not in the way when other operations are being performed, and it can be left in place all the time. It may also be easily removed and replaced when injured.

The clipping-faces b or B are very valuable, as it is well known that anvils continually wear out at this point, while by this arrangement the surface is all steel and if injured can be easily redressed or replaced by simply removing the steel face. The same thing is true of the steel plate I).

The set-screws c on the back of the attachment may be loosened to permit the attachment to be entirely removed, which will leave nothing but the fastening device 0 on the anvil, which does not take up much room and would not interfere with other operations on the anvil. It can therefore be left on all the time, and the attachment can be placed on it very quickly and easily. The bar d is intended to be adjustable with respect to the main part of the clamping device (1, so as to permit the treadle to be operated from different heights.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. An anvil attachment, comprising a body provided near one end with a vertical projection having an overhanging portion, and with a vertical longitudinal extension, said extension having its inner end terminating short of the projection and having an overhanging portion.
